摘　　要：利用Matlab的逐步回归分析程序从观察者给出的数据中进行选取,再通过多元线性回归拟和,得到在各线路有功潮流值基于各发电机组出力情况下,通过设立目标函数和约束条件建立了一兼顾阻塞费用的模型。调整模型的目标函数既限制了电价的快速增长,又尽可能降低了因调整产生的阻塞费用,证明了该方法的可行性和有效性。Using the Matlab stepwise regression analysis program which given by the observer,and then through the multiple linear regression fitting,we get the active power flow value of each line based on the output of each generator set,through the establishment of the objective function and constraint conditions to establish a blocking cost model.Adjust the objective function could limit the rapid increase of electricity price and reduced the congestion cost caused by the adjustment,the result proved the feasibility and effectiveness of the method.
